TO ALL WHOM IT MAY CONCERN:

Be it known that LYSIMEION MILLS, of Madisomin the county of Dane,'a'ndin the State of'Wisconsin,

have invented au'Automatic Draught-Iron for Connecting or CouplingRailroad-Cars; and Ido herein; declare that the followingis a full,clear, and exact description thereoi, reference'being had to theaccompanying drawings, and to the-letterspf reference marked thereon, Is

In the annexed drawings, making part of this specification, A representsthe draw-head of a railroad-ear, .which is constructed with aflaringmouth, as is customary. The lower side of this month has castupon it a lug or projection, which is bevelled on its front, but forms asquare shoulder at its back side. Upon each side of this lug orprojection, which stands in acentral positiomarerecesses or grooves, inwhich the sides'of the link lie when 'drawing' This'draw-head is castwith along slot from d to d in its upper side, and'with a shorter slotas seen, from o to o, in its lower side.

B represents a draw-bar, which is placed in the long slot in the upperside of the draw-head, and is there pivoted, as shown, near its rear endat :v. A pin, a, passes through the draw-head above the bar, a shortdistance from the pivot {Q1110 keep the forward end of the her fromrising too high; Cast or formed upon-the under edge of the bar, near itsforward end, are two hooks, C and D, of unequal lengths, and the lowerends of which project through the slot in the under side of the Hrawheid when the forward end of the her is down in drawing position. Backof the hook C is a; lug, 'E, which keeps the link from moving backwardwhen the cars are heing coupled. Before the bar B is pivoted in' thedraw-head, the link has its inner end caught by the hook "C; then, whenthe bar issecured in its place, the pin a'keeps its forward end fromrising high'enough to allow the link L to be drawn out, so that when alinkhas once been confinedin thisway inthe drawhead, itcannot be removedwithout first removing the bar B from its position, andit is thusprevented from being stolen or lost;

'Suflieient' room isleft'bene'ath the bar B to allow the link to he.shoved back its entire length when not needed, so that its forward endwill strike or lie against the lug or projection'I. Thus, when a link isnot in use,

it lies out of the way upon the bottom of the opening in the draw-head,andis prevented from jolting out by I the lug l.

Each draw-head is provided with n'link, but as only one link can be usedto couple two heads, one of the iiinks is pushed back into the beachesshown in red lines, fig. 2, while the other link .enters the draw-headand catches under'the hook D. -When the cars are drawing, or coupledtogether, one end of the'link is caught by hook-G of one draw-bar, andby hook D of the other. p I I This is a self-coupler. A hole may bemade, in the forward end of the bar B, and .a jointed rod, J,-con-'nected to it. Thistrod may rim to the top of the ear, for uncouplingby, when desirable,- from that position.

Having thus fully described my invention, what I claim as new, anddesiret'o secure by Letters Patent,is Thedraw-bar B, secured in thedraw-head .A, in the manner specified, tmd' provided with the hooks.U-nnd D, and lug E, as and for the purpose specified. i V I Intestimony that I claim-the foregoing, I have hereunto set m'y handfthis30th day of December, 1867.
